Scratchy RF gain knob on 535D

You can use contact cleaner, or just plain ole WD40, spray and work
the control back and forth a few times to break loose the
'dirt' and then spray again to rinse it away. Wait about 1 hour,
for the spray to dry, before using the radio again. WD and some
contact cleaners are a) flamable and/or b) conductive

Hello all,
I took a break from SWL for a few months (competing obsession), and
when I went to listen a couple of nights ago, I got a scratchy sound
from the speaker when adjusting the RF gain knob. On stereo
equipment, when that happens I pull the offending knob off, and spritz
the pot with some Radio Shack Tuner Control Cleaner & Lubricant.
However, I don't want to start spraying stuff into my good SW radio
without finding out what the risks, if any, are.
The radio is a JRC NRD-535D, bought on EBay about a year ago. Until
now it's been working pretty well. Is the spray cleaner the way to
deal with this problem? Or is there a better way to deal with it?
What do you all recommend?
Thanks,
DWP
Huh? How hot a spark can you make with 6 V?
